These products are used in various industries such as food and beverage, agriculture, logistics, and manufacturing, providing benefits like improved hygiene, reduced waste, and enhanced shelf life for products.

Chlorinated polyethylene (CM) is a synthetic polymer produced by the chlorination of polyethylene. It is a type of thermoplastic elastomer that incorporates chlorine atoms into the polyethylene chain. This modification enhances certain properties of polyethylene and gives CM unique characteristics, making it suitable for various applications. ### Key Properties: 1. **Chemical Resistance**: CM has improved resistance to chemicals, oils, and solvents compared to regular polyethylene.

Chlorinated polyvinyl chloride (CPVC) is a thermoplastic material derived from polyvinyl chloride (PVC) through a chlorination process. This process involves the addition of chlorine to the PVC polymer, which enhances the material's thermal stability, chemical resistance, and fire resistance. CPVC is known for its ability to withstand higher temperatures compared to standard PVC, making it suitable for various applications.

The Citroën Méhari is a small, lightweight, and versatile vehicle that was produced by the French automaker Citroën from 1968 to 1988. It is known for its distinctive design, which features a plastic body made from a durable material called ABS (Acrylonitrile Butadiene Styrene), making it resistant to rust and damage.

Commodity plastics are a category of plastics that are produced in large quantities and are typically used for a wide range of everyday applications. These plastics are characterized by their relatively low cost, ease of processing, and general availability. They are often used to manufacture a variety of consumer products, packaging materials, automotive parts, household goods, and more.

Conservation and restoration of plastic objects refer to the processes involved in the preservation and repair of plastic artifacts, often found in museums, collections, or archaeological sites. These practices aim to maintain the integrity, appearance, and historical significance of plastic items while ensuring their longevity for future generations. ### Conservation: - **Objective**: To slow down deterioration and preserve the object in its current condition.

Merrifield resin is a type of polymer resin commonly used as a solid support in solid-phase peptide synthesis (SPPS). It was developed by the chemist Robert Merrifield, who won the Nobel Prize in Chemistry in 1984 for his work on this method. The resin is typically made from polystyrene or a polystyrene-divinylbenzene copolymer and is functionalized with an appropriate linker that allows for the attachment of the growing peptide chain.

ECTFE, or Ethylene Chlorotrifluoroethylene, is a type of fluoropolymer that is known for its excellent chemical resistance, thermal stability, and electrical insulative properties. It is often used in applications where exposure to harsh chemicals or extreme temperatures occurs. ECTFE is commonly employed as a protective coating in various industries, including chemical processing, pharmaceuticals, and electronics.

Ionomers are a type of polymer that contain ionizable groups, which can be either cationic or anionic. These groups give the material unique properties that differ significantly from typical polymers. Here are some key points about ionomers: 1. **Structure**: Ionomers are typically derived from standard polymers, such as polyethylene or polypropylene, to which small amounts of ionic or ionizable groups are incorporated.

Masterbatch is a concentrated mixture of pigments and additives encapsulated during a heat process into a carrier polymer. It's used to color or enhance other polymers in plastic manufacturing. In simpler terms, masterbatch allows manufacturers to produce colored or specially formulated plastics efficiently and consistently. ### Key Features: 1. **Concentration**: Masterbatches are often produced in high concentrations of the required additives or pigments, which means that only a small amount is needed to achieve the desired effect in the final product.
